Being a police officer is a serious job, but even cops have to have a little fun sometimes.

One cop in Delaware apparently likes to let off steam by singing along to one of Taylor Swift’s hit songs.

In a Facebook post by the Dover Police Department, the video is said to be part of the department’s new series, “Dash Cam Confessionals.”

The hilarious footage of the officer, lip-synching and gyrating to “Shake It Off” while driving around in his patrol car is quickly going viral. The video has generated over 473,000 page views. The Facebook post has been liked and shared thousands of times.
